The Four-Stroke Cycle is a process used in many internal combustion engines, such as those found in cars and motorcycles. It consists of four distinct strokes: intake, compression, power, and exhaust. During the intake stroke, the engine draws in a mixture of air and fuel. Next, the compression stroke compresses this mixture, making it more explosive. In the power stroke, the compressed mixture is ignited, causing a small explosion that pushes the piston down, generating power. Finally, the exhaust stroke expels the burnt gases from the cylinder, making room for a new air-fuel mixture. This cycle repeats continuously, powering the engine.
